JUNCTION DIELECTRIC RESONATOR, BAND PASS FILTER AND DUPLEXER

摘要

PURPOSE: A junction dielectric resonator, a band-pass filter, and a duplexer are provided to reduce manufacturing costs by forming couplings with various strip lines with desired size and shapes through a printing operation. CONSTITUTION: A resonator(100) is formed into a cubical shape. A dielectric material fills in the resonator. A part with a conductive material(101) and a part without a conductive material(103) are formed on the outside of the resonator. A signal is passes through the part without the conductive material and is introduced into the inside of the resonator. The resonance is generated with respect to the dielectric material in the resonator.
